Talk:Cubic centimetre

Engine specs

I think this article needs an explanation of exactly how cc applies to engine specs, I personally don't know enough about it to explain it though Hypomanicmedic (talk) 10:31, 26 July 2009 (UTC)

Although strangely enough there is a diagrammatic illustration of the cylinders of an engine, which IMO seems very much out of place in a generic article about the cubic centimetre as a unit of measure -- could just as easily be a medical or chemical measuring device. 188.102.108.67 (talk) 19:51, 28 December 2015 (UTC)

Overdose

Someone really thinks we need a citation to prove that a hundred fold overdose of pretty much any medication can be dangerous or fatal? How is this fact not obvious? SkonesMickLoud (talk) 03:05, 23 December 2010 (UTC)

Revocation of 19 November 2011

Please discuss these changes at Wikipedia talk:WikiProject Measurement#Changes to the ledes of many SI-related articles. Martinvl (talk) 18:31, 19 November 2011 (UTC)

Restored as accurate and more neutral. If the discussion there does develop, and a consensus emerges which conflicts with the changes that I've made here, perhaps then would be the time to discuss the appropriate further changes to make here. -- de Facto (talk). 12:56, 21 November 2011 (UTC)

roughly

I think the word roughly is inappropriate for a discrepancy of less than three parts in a hundred thousand. OK, so my deletion of the word wasn't appropriate either, but I think a better word could be used here. Any suggestions? Plantsurfer (talk) 13:55, 2 June 2013 (UTC)

How about "The design criteria for the original prototype kilogram was that one gram (0.001 kg) of pure water its maximum density should have a volume of one cubic centimeter." Martinvl (talk) 17:04, 2 June 2013 (UTC)

Well yes, but that is making another point, isn't it?. My original criticism could be dealt with very simply by saying something like

"The mass of one cubic centimetre of water at 3.98 °C (the temperature at which it attains its maximum density) is almost exactly equal to one gram." The article on litre explains it very clearly as follows:

"A litre of water has a mass almost exactly equal to one kilogram of water. An early definition of the kilogram was set as the mass of one litre of water. Because volume changes with temperature and pressure, and pressure uses units of mass, the definition of a kilogram was changed. At standard pressure, one litre of water has a mass of 0.999975 kg at 4 °C, and 0.997 kg at 25 °C." Plantsurfer (talk) 17:42, 2 June 2013 (UTC)

While we're at it, another issue is that the second para leads with "Many scientific fields have replaced cubic centimeters with milliliters." An uninitiated reader might miss the irony that the litre is not an SI unit, whereas the cubic centimeter is. Plantsurfer (talk) 17:42, 2 June 2013 (UTC)

Possible incorrect conversion

I'm pretty sure 1cc must be equal to 1cl and not 1ml (which is a 10th of 1cl). The logic here is that a 500ml bottle would need to be 500cm high x 500cm wide x 500cm deep, which is huge as I'm 188cm tall and can easily hold a 500ml bottle in my hand. 92.2.89.152 (talk) 13:01, 29 May 2022 (UTC)

2 cm³ is two 1 cm³ cubes side by side, not a cube 2 cm on each side, which is 8 cm³. 500 ml = 500 cm³, equivalent to a rectangular prism 5 cm × 10 cm × 10 cm. Indefatigable (talk) 02:34, 30 May 2022 (UTC)
